Audio Edit

This subcategory collects 6 free tools that need no account and edit an audio file in your browser. They fit podcast editing, course track preparation, recording cleanup or sound adjustment before publishing. Tools include Trim audio, Merge audio files, Adjust audio volume, Audio fade in and out and Find silences in audio. Audio never leaves your browser when the tool page says so.

Start by identifying what must change. Trim audio extracts an exact passage, Merge audio files joins several files end to end with a gap if needed. Adjust audio volume normalises to peak or applies a gain and shows what clips. Audio fade in and out softens the start and end, Change audio speed speeds up or slows down while telling you how pitch moves. Find silences in audio lists or removes gaps with your own threshold and length. For a simple edit, trim then merge.

How to use

  1. Start by listening and marking the parts to keep: Trim audio extracts an exact passage, then Merge audio files joins the pieces end to end.
  2. Set the level with Adjust audio volume, watching what clips, then soften the ends with Audio fade in and out.
  3. If the pace feels wrong, use Change audio speed while keeping in mind how pitch moves, then listen again before validating.
  4. For spoken recordings, go through Find silences in audio with adapted threshold and length, then check that useful pauses remain.

Frequently asked questions

How do I remove gaps in a recording?

Find silences in audio lists or removes gaps in a recording, with your own threshold and length. Set these two values first so you do not cut useful pauses. Listen to the result before export. The tool is free and needs no sign-up.

Can I change speed without losing pitch?

Change audio speed speeds up or slows down a file while telling you how pitch moves. The tool shows that effect so you can decide. Test several settings and check the result by ear. The audio stays in your browser.

In what order should I edit a simple podcast?

Trim the passages with Trim audio, then bring them together with Merge audio files. Adjust the level with Adjust audio volume and finish with Audio fade in and out. If gaps are distracting, use Find silences in audio before export.

How do I change speed without making the voice sound strange?

Change audio speed tells you how pitch moves. Test light variations and listen to the voice over several sentences. If the result sounds artificial, return to a speed closer to the original. The audio stays in your browser.
